Myinvention relates to a hand carding device'for brushing or-strippingwool, cloth,

furs, hair, or other fibrous materials by means of closelyassembledteeth or points of wire 5 or other material set in a suitablesupport.

' Theinvention relates more particularly to a device wherein theassembled teeth or points comprising u shaped wires are inserted or setin a foundation sheet of rubber, leather or other pliable or flexiblematerial.

. ferredto which shall be simple, durable and which may bevcheaplyconstructed and in such manner that parts shall all be securedtogethenfirmly so thatthey will not'become loosenedduring use. 7 I I Afurther object is to produce a device of the character referred to whichshall present at its base or rear side oppositethe brushes and at allitsedges a smooth finished appearance free from-rougher salient projectionsoruedges and particularly as to'the back-shall; present if desired asmooth con-' tinued' surface. To these ends theinvention consistsin thecombination of parts and the elements or details of construction hereinafter'more particular specified in the-claims.

In the accompanying drawings: I Fig; 1 is a general perspective-viewofthe elements of the device arranged in their relative position but indisassembledrelation;

' I foundation lies against'thecover plate acting asa backing'for thefoundation.

;One of the objects of my invention is to providea device of the generalcharacter re-l 1y described and thencompleted and seenon the brush orpoints I f I v instance bythe plate or member forming the a verticalcross-sec'tion'iof the deig. 2, inthe line of the haIndle portion.MwthereQfy 40' ification.. I V II .Fi s and-6 showmodifications in"the" 3 and other figures, after the foundation'has 1 indicates theleather, rubber or other foundation usually of flexible or pliablecharacter'in which the teeth or points of the card are set. Said teethor pointspreferably consist, as indicated, of U-shaped piecesof wireinserted through the foundation and prevented from pulling out by thecross member of the U which lies upon the back of the foundation. 2indicates a rigid integral frame preferably of. metal adaptedto form arigid or solid continuous supporting frame for the foundation supportedtherein upon the ledge or flange extending inwardly from I the verticalmember of said frame as shown inFigs. 3, 4 and 8. In order to hold thefoundation firmly in its place and stretch it on said frame the saidledge of the frame may be providedwith the metal ears or points 4 whichare preferably integral'with the frame and engage the edge ofthe'foundation from the bottom side and securelyhold saidfoundation-stretched in place. Said projections, teeth or points 4 maybeformed upper side as clearly shown in Fig. 7 fora purpose to bepresently described. At 5 is indicated a backing for the foundation,said backing comprising a plate of suitable mate-' rial, preferablymetal,- which lies upon the back of the foundation and against the baseof the U-shaped wires and is secured in position thereonbyf-anygsuitable means, as for cover'orback plate'and to which the frame2 v r catedat 6;and forthe purpose of-fasteni'ng". is a partial sectionshowinga modthe' frame and back plate together theedge ofthe back platemay be turned over'the flange 2 ofthe frame as indicated at6, Fig.

been securedlin placein the frame 'andlthe" foundation havingbeen,attached by its edges described completes -the-structure.- The to theframe 2-by means of the points 4, they eifect of forcibly turning downthe edge of the backing plate over the flange 2 to lock the partstogether will be to cause the upper portion of the frame 2 carrying theteeth 4- to expand or rock outwardly lightly thereby exerting a slightpull upon the foundation and stretching or putting tension on the sameand thereby helping to make it comparatively rigid. The manner ofincorporating the handle device in the structure will now be described.

As shown in Figs. 1, 2 and 3, the back plate 6 is provided as indicatedat 9 with an opening in its flange or downwardly extending edge throughwhich projects the handle shank S. Said handle shank is of metal and isintegral with the backing 5. The handle proper indicated at 10 may bemade of wood or other material and is secured to or forms an extensionof the shank S in any usual or desired manner. Said handle shank orhandle might be made integral with the top or cover plate (3 asindicated at 8, Fig. 6, or might be made integral with the metal frame 2as indicated in Fig. 7 at 8. If desired said shank may be made in partof a projection 8'. integral with and projecting from the cover 6 and asimilar co-operating part projecting from and inte ral with the loweredge or portion of the frame as shown in Fig. 5. The two co-operatingshank members 8 together form in this instance a shank for reception ofthe end of the handle. It will be obvious that in each of the cases justdescribed the handle shank might be extended with the handle proper sothat the handle, its shank andt-he element of the device from which theshank projects would be a single or integral plece.

As shown in Fig. 4 the frame and the back or cover 6 may be fastenedtogether by in- 1, denting the downwardly projecting flange 6 of thecover to engage it with the upwardly pro ectlng member of the frame 2 asindicated at 7 As will be obvious, in this instance the overhang 2'would be dispensed with; also the inturning of the downwardly projectingedge or flange of the cover plate would not in this instancebenecessary. As indicated in Fig.

9, the use of a separate backing plate 5 might be dispensed with and theinside of the cover plate form the backing for the foundation wvhich inthis instance would lie directly in contact therewith. Also thedownwardly and inwardly turned edge of the cover plate would be thecontinuousrigid supporting frame for the foundation asjalre'adydescribed, in which case the use of the separate frame 2 would beunnecessary. In this instance and as shown the inwardly turned flange ofthe frame would as before be provided with the means for fastening thefoundation in stretched or extended position,

said edge being provided with the ears, teeth or points struck uptherefrom and passing through the foundation and locked by overturningthem on the inside thereof. The

the combination of a wire carrying foundation, an integral rigid frameforming a rigid border enclosing the edge of the wirecarryingfoundation, a backing cover plate and means integral with the coverplate and frame interlocking them with one another to hold the partstogether.

2. In a device of the character described, the combination ofarfoundation carrying wire points, a rigid frame forming a continuouslyrigid integral border around the edge of the foundation and within whichsaid foundation is supported, a top plate and means integral with saidframe interlocking with an integral portion ofthe top plate for securingthe parts together.

3. In a device of the character described, the combination of afoundation carrying wire points, a rigid frame forming a continuousintegral rigid border around the edge of said foundation and withinwhich the same is supported, a plate lying upon the back of thefoundation, and acover plate interlocking with the frame and holding thefoundation and plate together in position within said frame. r

4. In a device of the character described,

the combination of a wire-carrying foundation,a frame forming a rigidintegral border around the edges of the'fouiidation and within whichsaid foundation is supported, a cover plate, a backing plate interposedbetween the back of the foundation and said cover plate, means forsecuring the frame to the cover plate comprising interlocked integraledges of said membersand a handle shank integral with an element of thedevice.

5. In a device of the character described,

frame consisting of an integral continuous border enclosing'the, edge ofthe foundation and to whichsaid foundation is secured, a backing plate,a cover plate, means for" securing said parts together by interlockededges of the frame and coverplate, and a handle shank projecting from anelement 7 of the device and integral therewith.
